Russia and Ukraine report fake alerts after emergency app attacks, outlets say

What happened

The Cyber Express reported on 2 November 2026 that emergency apps in Russia and Ukraine were “hacked with fake threat alerts” (The Cyber Express). On 3 November 2026, DataBreaches.net reported that Ukraine and Russia both say fake emergency alerts appeared after cyberattacks targeted apps, as a limited ceasefire ended (DataBreaches.net).

This advisory is based on the headlines only. The full articles could not be reviewed. The following are not confirmed: which apps were affected, how they were compromised, who was responsible, how many users received fake alerts, and what the alerts said. Neither outlet’s headline names an attacker. We found no official advisory in the sources.

Am I affected?

Not confirmed. The headlines say emergency alert apps in Russia and Ukraine were targeted, but they do not name specific apps, versions or platforms. If you do not use emergency alert apps in either country, these reports do not indicate that you are affected.

What to do now

1. If you receive an unexpected threat alert in one of these apps, check it against another official source before acting. This is a general precaution, not guidance from the sources.
2. Watch the linked reports and official government channels for confirmed details, such as which apps were involved and any fixes.
3. Do not share screenshots of unverified alerts as fact.
